:0 3 A still further object is to provide a band forproperly-securingthe patlent in the seat.

A further object is to provide means for adjusting said band toaccommodate larger or smaller zlpa-tients and a still further object :5is to provide'n'ieans for adgusting the standard employed for holdingthe head stall.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims. to In the accompanying drawingsforming part of this application, Figure 1 is a perspectiveview ofthechair complete. Fig. 2 is a central vertical sectional view throughthe chair, and Fig. 3is a horizontal sectional L5 view through the chairat a point above the ,seat I Referring to the drawings in which similarreference numerals designate corresponding parts throughout the severalviews, 1

' 0 indicates the frame of the chair which may be constructed intheusual or any preferred manner, the rear post of the frame beingprovided with a back 2, while forwardly of said back is a platform 3 andextending up- 5 wardly fi am the platform are arm rests 4, although twill be clearly understood that these parts may be constructed tobestsuit the occasion.

Mounted upon the platform 3 is a seat proper 5, which is held inposition on the platform by introducinga bolt. (3 through the seatandplatformand in order to permit said seat to readily rotate, curvedplates 7 and 8 are embedded in the platform 3 and seat 5, respectively,said plates forming a race for bearing balls 9, the diameter of saidballs being such as to space the scat a distance from the platform, sothat the pa tient may readily rotate the seat to change the position ofthe body.

In order to hold the seat in its adjusted Patented Mar. 8, 1910.

position, a strap 10 is fixed at its longitudinal center tothe rear edgeof the seat, the ends of the strap extending forwardly and intoengagement with any suitable form of spring clamps 11,.whicl1 clampsserve to hold the ends of the strap a ainst. longitudinal movement whenthe strap is securely engaged with the clamps and it will be readllyseen that by releasing. theclamps, the seat may ,be rotated tOll1(pI'0])Gt position when the clamps. are again engaged with the strap andas the clamps are positioned 111 convenient reach of the patient, theadjustment of the seat can be readily accomplished by the patient. Theseat 5 is providetlav'itli a covering 12,

of any suitable material, preferably leather and to said coverin isattached a .Jlllld. 13,

also preferably of leather, said band having its lower edge attached tothe covering by means of a lace 14 or otherwise and \by providing thatportion of the covering ad- ]acent the side edges of the seat withseries of openings 15 to receive the lace, said band may be adjusted tofit around patients oft.

various sizes and in ordenjo securely clamp the band around the hips ofthe patient, the upper forward edges ofthe band are provided withtongues 16 to one of which is attached abuckle 17 and to the other apositioning the band around the patient and extending the strap 18through the buckle 17 and drawing the same taut, the patient .willbesecurely strapped to the seat.

The back 2 is provided with slots 19 and 20, which slots are arranged inpairs and on opposite sides of the vertical center of said back, saidslots being preferably ar-' ranged at an angle to the vertical center ofthe'back and each parallel with each e the inner ends of-the bolts areattached shoulder straps 24 and 25, respectively, said and over the Ithe chair.

upper portion of the straps bein adapted to extend around the shoulders01 the atient and form a support at this point and in view of the lengthofthe slots through said straps maybe adjusted to accommodate patientsvarying in height,

Adjustably attached to the rear of the back 2 and-preferabl at thevertical center thereof is a standar 26, said standard being providedwith vertically extending slots 27, through which extend bolts 28 and bymeans of which the standard is held in engagement with the back, theouter ends of the bolts being threaded to receive w'ng' v nuts 29, whichbind ag ainst the stand rd and. hold the same in itsyertical adjustedposition.

At the upper end of the standard 20 is an inwardly 'jects forwardlyover-the back of the c air In order to su ort the head of the tient, ahead stall which is adapted to fit aroundvand over the head,-one partof'the stall having'achin strap 32, which isadapted to extend below thechin of the patient and in the rear of the chin strap is a neck strap33,which is adapted to extend in the rear of the "head adjacent the neck ofthe patient and in order to operate the head stall, a cable 34 isattached to the upper portion of the stall and extended upwardly throughanopenin 35 in the .free end of.

the section 30, said cable thence extending over sheaves-36 and 37 "onthe section 30,

thence downwardly and around a sheave 38 attached to the lower end ofthe back 2, from whence said cable extends over the platform 3 to apoint adjacent the forward at one edge thereof, the free endof saidcablebe'ingse cured by a spring clamp 39 and as said clamp is positionedadjacent one of the,

I clamps 11, it

will be in convenient reach of thepati'ent when occu ying the chair.

-By arranging the (l 6VlC8 as herein disclosed, it Will be readily seenthat the W1- rious parts thereof may be adjusted by the patient whileoccupying the chair and if the patient finds that one position becomeswhich the bolts ext end,
